Patent number: 6706624Abstract: A method for making a multichip “HDI” module includes the step of making a substrate for supporting the semiconductor or solid-state chips by applying electrical conductor in a pattern to a first dielectric sheet, and applying encapsulating material to the electrical conductor. Apertures are made in the first dielectric sheet at locations at which the chips are to be located. The chips are affixed to a second dielectric sheet at locations registered with the apertures in the first sheet, and the sheets are juxtaposed with the chips extending into the apertures. Electrical connection is made to the pads of the chips by means of a multilayer structure of dielectric sheets with conductor patterns, interconnected by means of plated-through vias.Type: GrantFiled: March 18, 2002Date of Patent: March 16, 2004Assignee: Lockheed Martin CorporationInventors: Christopher James Kapusta, Thomas Bert Gorczyca

Patent number: 6602739Abstract: A method for making a multichip “HDI” module includes the step of making a substrate for supporting the semiconductor or solid-state chips (or other components) by applying electrical conductor in a pattern to a first dielectric sheet, and applying encapsulating material to the electrical conductor. Apertures are made in the first dielectric sheet and encapsulant at locations at which the chips (or other components) are to be located. The components are affixed to a second dielectric sheet at locations registered with the apertures in the first sheet, and the sheets are juxtaposed with the chips extending into the apertures. This results in the formation of gaps between the components and the edges of the apertures, which gaps are then filled with hardenable or curable material. Electrical connection is made to the pads of the chips by means of a multilayer structure of dielectric sheets with conductor patterns, interconnected by means of plated-through vias.Type: GrantFiled: March 19, 2002Date of Patent: August 5, 2003Assignee: Lockheed Martin CorporationInventors: James Wilson Rose, Thomas Bert Gorczyca, Christopher James Kapusta, Ernest Wayne Balch, Kevin Matthew Durocher

Patent number: 6255137Abstract: A method for making an HDI-connected circuit is described, which in a simple manner allows an air pocket, space, gap, or bubble to be formed over pressure- or dielectric-sensitive portions of a semiconductor chip. The method applies a layer of uncured adhesive over a dielectric film, and also over any electrical conductors deposited on the film. The adhesive is exposed through a mask to a laser beam, which selectively vaporizes the adhesive in the exposed regions, to define the air pocket region. The semiconductor chips are applied, electrode-side down, on the adhesive, with the sensitive regions registered with the pockets. The adhesive is cured, and conductive vias are formed through the dielectric film and the adhesive to make contact with the electrodes of the semiconductor chips. Other layers of HDI interconnect are then applied over the dielectric film, and interconnected by vias, if needed.Type: GrantFiled: July 1, 1999Date of Patent: July 3, 2001Assignee: Lockheed Martin Corp.Inventors: Thomas Bert Gorczyca, Herbert Stanley Cole
